HAY-PRESS- Specification of Letters Patent.

Patented June 25, 1907.

Application filed November 2, 1905. Serial No. 285.593.

To all whom it may concern.-

Be it known that I, J OSEPH DAIN, a citizen of the United States,residing at Ottumwa, in the county of Wapello and State of Iowa, haveinvented certain new and useful Improvements in Hay-Presses, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to hay presses, and has for its object to providecertain improvements which will be hereinafter particularly pointed out.Such improvements relate to the means for tucking in the ends of the haywhich project when the plunger is retracted, and to the connectionsbetweenthe devices for actuating the plunger and the mechanism forreciprocating the same.

What I regard as new is set forth in the claims.

In the accompanying drawings,Figure 1 is a side view of a hay press,some parts being omitted; Fig. 2 is a perspective view of myimprovedtucker; Fig. 3 is a partial longitudinal sectional view of a haypress, showing my improved-tucker; Fig. 4 is a plan view thereof; Fig. 5is a plan view of a part of the operating mechanism; Fig. 6 is anunder-side view of certain of the parts illustrated in Fig. 5; Fig. 7 isan inverted section on line 77 of Fig. 6; Fig. 8 is a perspective viewof the bearing block; Fig. 9 is a section on line 9-9 of Fig. 5 Fig. 10is an underside view of the parts shown in Fig. 9; Fig. 11 is asectional view, showingthe normal position of the tucker; and Figs. 12and 13 are similar views, illustrating its operation.

My present invention consists primarily in a tucker so mounted withrelation to the baling case or chamber and the compressing mechanismthat the inwardly-projecting portion thereof moves rearwardly with theplunger as the latter recedes, and at the same time moves inward,thereby very efficiently tucking the projecting ends of the hay down sothat when the next succeeding charge is introduced and compressed thereare no loose ends of hay between successive charges. To secure thisoperation the transverse axis, so as to move the inwardlyprojecting endlongitudinally of the press, and at the same time the tucker is arrangedto be movable bodily in and out relatively to the baling chamber.Usually and preferably tucker is pivotally mounted so that it may rockon a l thejtucker is mounted on the top of the bal ing case, but I donot restrict myself to so mounting it. In the best embodiment of myinvention the tucker is pivotally mounted on suitable pivots preferablyformed by the rear portion of a bail, the forward end portion of whichis pivoted upon the top of the baling case. The bail is of such lengththat the tucker is supported at the forward edge of the feed openingwith its lower edge or lip projecting into the baling chamber, and theparts are so adjusted that of the lip normally lies slightly above theupper surface of the plunger. Suitable springs and stops are providedfor restoring the tucker to its normal or upright position.

Referring to the drawings for a more particular description of thisfeature of my invention,l1 indicates the frame of the press; 12 thebaling case; 13 the baling chamber; 14 the feed opening; and 15 theplunger,all of which are of the usual construction.

16 indicates the top of the baling case.

17 indicates the bail, which is pivoted, preferably to suitable lugs 18on the top of the baling case and projects rearwardly therefrom, asshown in Fig. 3.

19 indicates the tucker, which, as shown in Fig. 2, is in the form of aplate which extends transversely of the baling case and is pivoted uponthe rear portion of the bail 17. A plate 20, as shown in Fig. 2, servesto secure the tucker 19 to the bail 17.

21 indicates the tucking edge or lip of the tucker 1 9, which ispreferably curved forward slightly, as shown in Figs. 2 and 3, andprojects down into the baling case at the forward edge of the feedopening. The lower edge of the lip 21 lies slightly above the uppersurface of the plunger 15, so as not to interfere with the free movementthereof.

22 indicates a flange at the upper edge of the tucker 19, to which areconnected springs 23, as shown in Figs. 2 and 3. Said springs extendforward and downward, and are connected in any suitable way, as by lugs24, with the top of the baling case, so that they serve to draw theupper portion of the tucker 19 forward.

25 indicates a crossbar or'rod, the ends of which are secured to theside boards 26 at the opposite sides of the feed opening, as

l shown in Figs. 2 and 3. Said rod 25 serves the loweredge as a stop tolimit the forward movement of the upper portion of the tucker, so thatthe springs 23 cannot move it beyond a'pproXimately a vertical position.

In compressing, the plunger 15 moves to the right as shown in Fig-1,forcing the hay in advance of it into the baling chamber. As the plungeradvances and the hay becomes more dense its pressure upon the lip 21moves said lip forward with the hay to a greater or less extent, andwhen the plunger approaches the lip 21 of the tucker said lip is forcedupward as well as forward by means of the hay which lies between it andthe plunger. When the plunger is withdrawn the springs 23 immediatelyforce the tucker inward and at the same time pull the upper portion ofthe tucker forward thereby throwing the lip backward. In this way theprojecting ends of the hay are pressed back and down so that they are inproper position to be folded in when the next succeeding charge of hayis compressed. The tucker also assists in returning the plunger aftereach compression, since the pull of the springs 23 is transmitted to theplunger through the tucker and its lip 21. INhile said lip does notdirectly engage the upper surface of the plunger, it engages itindirectly by means of the hay tightly wedged between said parts.

WVith regard to the operating mechanism for the plunger, my inventionhasparticularly to do with the connecting devices between the plunger andthe horse-power mechanism. As shown in Fig. 1, the frame 11 extendsforward and is connected with the axle 27 of the front wheels 28, andnear its forward ends said frame carries a casting 29 in which ispivoted a swinging link 30 connected by a connecting rod 31 with theplunger. Said link 30 is adapted to swing back and forth through agreater or less are to reciprocate the rod 31 and plunger, and isoperated by means of a sweep 32 carrying operating arms 33 which projectat an angle thereto, as shown in Fig. 5.

34-35 indicate braces for the sweep 32.

As best shown in Figs. 6 and 7, the link 30 is provided with a pivot 36which fits in a suitable bearing in the casting 29, and is provided witha laterally-projecting lug 37 which projects beyond the bearing of thesaid pivot under the adjacent portion of the castin 29, as shown in Fig.6. As also shown in Fig. 6, the bearing of the pivot'36 is circular,except that it is provided at one side with a recess 38, of such shapeas to permit of the passage of the lug 37 when. the pivot 36 is insertedin its bearing. Preferably the outer portion of the lug 37 is rounded,and the recess 38 is consequently made semicircular, but this is notessential. In order to fill up the recess 38 and furnish a continu- 42may ous bearing for the pivot 36, I provide aboaring-block 39 shaped toconform to said recess,its inner surface being curved in the arc of acircle of the same diameter as the pivot 36, so that when said block isin place a continuous semicircular bearing surface is provided for saidpivot. To hold said block in place it is provided at one side with aprojecting lug 40, which fits into a suitable recess provided in theupper surface of the casting 29, as shown in Fig. 7, and indicated bydotted lines in Fig. 6. The link 30 does not swing'entirely around, andthe lug 37 is so placed that under normal working conditions it neverregisters with the block 39, consequently the pivot 36 can neverjump outof its bearing. The block 39 cannot become displaced under suchconditions because, as shown in Fig. 7, it is overlapped by the link 30.To remove the link, it is swung far enough to bring the lug 37 intoregister with the block 39, when the link and said block may be removedtogether.

In Figs. 9 and 10 I have shown a somewhat similar arrangement forconnecting the link 30 with the connecting-rod 3 1,there being a pivot41 carried by the outer end of the link and having a lug 42 projectingunder the rear portion of the connecting-rod 31. The lug be insertedthrough a recess 43. If desired, a block may be employed for thisconnection also.

44 indicates a bumper, against which the outer end of the link 30strikes when the plunger rebounds at the end of each stroke.

Instead of actuating the link 30 by the operating mechanism shown, anyother suitable means may be employed. In the construction shown the arms33 carry rollers 45, which engage the operating edge of the link 30 asthe arms rotate and force it backward until said rollers run off the endof said link and thereby release it so that the plunger is permitted torebound under the elasticity of the hay.

So far as I am aware, no one has heretofore employed a tucker having themovement hereinbefore described, and I therefore claim such constructionbroadly. In other respects also my invention is not restricted to theconstruction illustrated and described, except in so far as particularlyclaimed.

That which I claim as my invention and desire to secure by LettersPatent is,-
